Description of problem:
When signing mail Evolution forces base64 or quoted-printable for the
purpose of reducing the likelyhood of mail gateways modifying the body
and making the signature unverifiable.
However, this causes serious problems when the mail has to be read by
programs that do not understand these encodings (such as Linus Torvalds' patch
Furthermore, if mail is sent directly rather than through an ISP
smarthost (and the MTA on localhost isn't broken), mail can only
corrupted by the recipient (that presumably is capable of correctly
configuring a mail server).
This patch adds a couple of options to allow non-base64/quoted-printable
encodings in GnuPG signed mail and in S/MIME signed mail.
If you consider my implementation unacceptable, please still consider
the feature request and provide an alternate implementation.
The S/MIME part is untested.

Upstream didn't accept the patch and we're not going to fork to add new options
and change UI. Additionally, fejj's reply as to why the patch isn't accepted
upstream applies equally here.
